This recent cold weather, and some of the posts here regarding it, have gotten me thinking about frostbite.

What is the best way to protect your face? The bank robber style face mask seems like it should cover the vulnerable spots, but I find they get wet from breathing condensation. Do the mouth and eye holes expose frostbite-prone skin?

What did the old-time Yukon trappers do? Or was frostbite the least of their worries?

And a somewhat related question. On heavy arctic parkas, why is there fur around the opening of the hood? The hood is still wide open. I understand the insulating effect of fur against your body, but why around the opening? It can't be just for decoration.

I'm interested in any info. Thanks!
